39Thedition of the国际高级陶瓷和复合材料会议opened Monday in Daytona Beach. While the northeastern United States braces for an epic snowstorm, about 1,100 scientists and engineers from around the world are here to attend symposia, give presentations, network, and meet customers and vendors at the expo.

程序主席Soshu Kirihara开幕了会议。今年,近一半的与会者来自大约40个国家,这可能是本次会议有史以来最大的国际特遣队。同样,今年,会议接受了创纪录的摘要数量,因此散落到酒店的其他一些地区。

David R. Clarkeopened the plenary technical session with the James I. Mueller Award lecture on materials selection of next-generation thermal barrier coatings (TBC) for gas turbine engines. About one-third of the U.S. natural gas supply generates about 40% of the nation’s electric power. “Gas turbines can displace a lot of coal,” Clarke says. Natural gas has a high energy density, and one gas turbine produces more power than the world’s largest solar power plant.

TBC通过允许涡轮机运行镍基底底物可以耐受性能来提高涡轮机的效率。克拉克的数据表明,在过去40年中,超合金底物的温度极限仅增加了约100°C。YTTRIA稳定的氧化锆(YSZ)TBC每毫米厚度的工作温度约为一个程度。TBC通常厚150-200微米,因此“购买”高达200°C的工作温度和效率。

克拉克(Clarke)建议,将来,涡轮陶瓷基质复合材料也可能会用TBC代替超合金基板。嵌入TBC中的发光离子可以用作原位传感器。仍然存在一些挑战,包括NOX排放,这些排放限制了最大燃烧温度。在较热的发动机中,摄入的沙子和污垢可以用玻璃状沉积物融化并抓住涡轮机。金属成分对二氧化硅腐蚀的敏感性仍然是一个空旷的问题。

Sanjay Mathur—the 2015 Bridge Building Award winner—presented his group’s work on chemical processing of nanostructured ceramics. “Precursor chemistry influences where a material is going,” Mathur says. Using energy and healthcare applications as examples, Mathur showed how precursor chemistry of inorganic materials influences functionality of the final product. For example, doping small amounts of nitrogen into titanium dioxide increases bioactivity of nanoparticles for osseointegration.

他展示了如何通过化学加工来针对非常不同的应用在纳米级上设计一种材料。他展示了他的小组的工作合成用于MRI应用的氧化铁纳米颗粒,并作为用光为氢经济拆分的催化剂。

颁奖演讲进行了两次全体会谈。谈判满足了全体会议对一般兴趣的期望,从技术上讲是有趣的,但“在杂草中”不太感兴趣。

首先是卡托·劳伦金。劳伦金(Laurencin)是一位明星 - 他的简历很容易使他的(非常聪明,成就率很高的)观众感到懒惰。但是,他迅速将自己作为一名材料科学家(我们中的一个人”的材料资格,这是为了将材料设计成组织,这也要求他成为外科医生和生化研究人员。

Laurencin在“再生工程”新领域的最前沿工作。该野外工程师材料促进组织生长,以使材料不能代替人体,而是以各种方式促进组织的生长和重建。劳伦金(Laurencin)作为一名骨科医生,研究了肌肉骨骼问题,并用膝盖证明了他的观点。

The field of regenerative engineering is young—only about 25 years old. Laurencin reviewed its history and some of the field’s successes, for example with bone scaffolds that promote bone growth and dissappear as the growing bone absorbs their chemical constituents. Today, the field is much broader and amazing advances are being realized by integrating tissue with advanced materials and stem cells.

例如,劳伦辛说,可以从“感应材料”中创建任何组织类型(肌肉,肌肉,韧带,软骨和皮肤)。他解释说:“拿一个干细胞,将其放入正确的材料中,您可以使其分化为所需的东西,而没有其他生物学因素。”他通过将干细胞放置在右矿物环境中,并精确地控制钙离子从磷酸钙 - 聚合物复合材料中释放出来,展示了体内骨骼内建造的典范。

干细胞来自缺乏道德问题的来源。

劳伦金问观众:“你们中有多少人胖?你们当中有多少人喜欢脂肪在身体上的位置?”研究人员已经学会了如何将成年干细胞与脂肪分离。这消除了移植的免疫力问题,因为干细胞来自患者。他没有问,但我敢打赌,大多数中年和年长的听众都是“全部耳朵”,因为他们的膝盖交易前景。注册!

The final plenary speaker waskazushige ohno日本的Ibiden的著作,他谈到了柴油颗粒过滤器发展的趋势。他指出,柴油烟灰是仅次于二氧化碳排放的全球变暖的第二大贡献者。排放控制有两种方法:减少或减少NOX。

Ohno outlined advances in silicon carbide filter technology, which includes some interesting balancing between crack formation to generate porosity, but not so much as to crumble. Ohno anticipates that in the mid- to late-2020s, precious metal catalysts will be replaced with zeolite catalysts.

午餐休息后,技术计划认真进行。我坐在里卡多·卡斯特罗(Ricardo Castro)的全球青年调查员奖演讲中。显然,卡斯特罗(Castro)是一位精湛的老师,带领观众通过水合对纳米颗粒表面能量的基本热力学开创性,然后展示知识如何以YSZ为例指导纳米颗粒的工程。

ICACC shows some signs of being “all grown up” with two notable second generation presenters. Shirley Zhu, daughter of ICACC regular Dongming Zhu, presented results from her work as a summer intern atNASA Glenn研究中心在碳化硅添加剂制造上。朱于5月完成了她在化学工程学院的本科学位。在同一研讨会上,高中大三学生安东·塞勒姆(Anton Salem)介绍了他的作品,他也曾在NASA Glenn Research Center担任Glenn高中实习生。他的父亲乔纳森·塞勒姆(Jonathan Salem)是合着者之一。两个年轻人都表现出色。

会议进入“中年”时的未来看起来很光明。越来越多的年轻人在这里 - 大约有200名学生和相当多的年轻专业人士。沃卢西亚县(Volusia County)发布了新闻稿,称该会议每年为150万美元的业务带来。明年40的计划Thjubilee celebration are well underway.

所有身体健康的迹象!
